Introduction to BSS & FSS Plans
By Jian WANGBR/SSD/SNP
ITU HQ Geneva, 3 December, 2018
Why We Need Plans
Plan Approach
Plans Features and Parameters
Space Plans Procedures
Summary
Agenda
ITU Constitution
• Article 44Radio frequencies and any associated orbits are limited
natural resourcesMust be used rationally, efficiently and economically in
conformity with the RRTo have equitable access to those resources
• Article 45Not to cause harmful interference to the service operating
in accordance with the RR
Radio Regulations
Mechanism to control interference
Allocation
Coordination / Plan
Technical and operational limit
Licensing
Monitoring
Two Different Approaches
Coordination
First come, first servedbased on current requirement
Planning
Distribution of resources based on current and future requirement
Efficient /economical Equitable access
late comers may not have access to as the early users have consumed all.
Planning Approach
It is a distribution of some of the spectrum/orbit
resources based on current and future technical
requirements
Provides equitable access as each ITU Member State
gets a pre-determined allocation of part of the
spectrum/orbit resources protected from harmful
interference for current and future use.
Planning Approachthe “Space Plans”
Broadcasting-SatelliteService and feeder-link Plans
• 11.7-12.2 GHz (Region 3)
• 11.7-12.5 GHz (Region 1)
• 12.2-12.7 GHz (Region 2)
• 17.3-18.1 GHz (Region 1&3)
• 17.3-17.8 GHz (Region 2)
• 14.5-14.8 GHz (Region 1&3 except Europe)
• 4500 – 4800MHz
• 10.7 - 10.95 GHz
• 11.2 - 11.45 GHz
• 6725 - 7025 MHz
• 12.75 - 13.25 GHz

FSS Plan
Space Plans, a long HISTORY
• WARC-77 established the Region 1&3 BSS Plan
• RARC-83 established the Region 2 BSS and associated feederlink Plan
• WARC ORB-85 included the Region 2 BSS and associated feederlink Plan into the Radio Regulations
• WARC ORB-88 established the FSS Plan and Region 1 &3 BSS feeder-link Plan
• WRC-97 revised the Region 1&3 BSS and associated feederlink Plans
• WRC-2000 revised the Region 1&3 BSS and associated feederlink Plans
• WRC-07 revised the FSS Plan
• WRC-12, WRC-15 and ……. Revised provisions related to date of bring into use, comments for R1&3, transfer to digital emissions for R1&3….
Simplify the procedures and consider the development of technology
Space Plans features (1)
To guarantee equitable access, it is based on a reservation of capacity for future use by the ITU Member States:
Not all Plan assignments are currently in operation BUT will not be cancelled and are protected from harmful interference from other networks
Standard parameters (assumptions) are required to ensure equity amongst Administrations and possible future use
Space Plans features (2)
To guarantee equitable access, the beams cover the national territory of each Administration:
National Coverage
National service area
Space Plans features (3)
Protection from harmful interference is provided based on the
Plan characteristics and NOT on the characteristics entered into
the Master Register at notification stage. This is different for
networks operating in the non-plan frequency bands.
Space Plans features (4)
To use the space resources rationally, efficiently and economically, the Aggregate C/I method is used to identify potential interference.

Interfering assignments
(C/I)agg= (C/I1) (C/I2) (C/I3)

I2 I3C
Space Plans features (5)
Standard parameters (main assumptions with some exceptions)
Same amount of frequency band for each beam
National coverage
Elliptical beam using defined space station antenna pattern
Defined C/N
Same values of system noise temperature
Similar power level
Defined earth station antenna size and pattern
Defined Aggregate C/I
BSS Plan and FSS PlanSome distinct features
APPENDICES 30/30A
BSS Plan
• Plans separated by Regions
• Assignments Plans
• Shared with other space services in other Regions
• Lists for R1&3 only
• Cluster concept in Region 2 Plan
APPENDIX 30B
FSS Plan
• World wide
• Allotment Plans (conversion to assignments before use)
• Together with single entry criteria
• Protection based on grid points in service areas for downlinks

key points to remember
• Plans ensure equitable access and equitable use of frequency and
orbital resources
• Plan and non-plan procedures have similarities and differences
• In the Radio Regulations, Appendices 30/30A/30B contain the
Plan/List/MIFR processes and definitions
• Processing deadlines should be carefully tracked
• It is important to comment when your Administration is identified as
potentially affected by new assignments
